# bad bench — full benchmark runner in Docker (no GUI needed)
#
# Uses Xvfb (virtual display) so Chrome runs "headed" with full stealth
# fingerprinting, without requiring an actual monitor or X server.
#
# Build:
#   docker build --platform linux/amd64 -f Dockerfile.bench -t bad-bench .
#
# Run full WEBBENCH-50:
#   docker run --platform linux/amd64 --env-file .env \
#     -v $(pwd)/agent-results:/app/agent-results \
#     bad-bench
#
# Run specific cases:
#   docker run --platform linux/amd64 --env-file .env \
#     -v $(pwd)/agent-results:/app/agent-results \
#     bad-bench --cases bench/scenarios/cases/webbench-reachable4-max20-timeout120.json
